Clothes peg/pin zippers - how to automate?
 

I love a clothes peg zipper, as both dom and sub. The fear one sees in the eyes of the sub, or the dread felt as you wait for what you know is coming is exquisite.

However, I've been trying to think of a way to automate the "yanking" part. I can't think of an engineering item that really works in the way I would need it to - waiting for a time to build up the suspense, then making a short movement to pull the zipper.

Any ideas as to how I could create such a device?

Some form of weight with a time release perhaps?

Yes, I think you're right - the weight is essential for "the pull". Simple springs and jack-in-the-box level technology just isn't going to be able to generate the power to rip, say, ten pegs off, with any degree of satisfaction.

That's actually much simpler...I think you might have the solution there. Just a timer to release the weight, and Bob's your uncle.

i look forward to the testing reports ;)
